Solution of first question:
Let f(x) = 0
5x+2=0
5x = 0-2
x = -2/5
f(-2/5) = 5*-2/5+2
f(-2/5) = -2+2
f(-2/5) = 0
Hence, f(-2/5) = 0 is the value of the given polynomial.
Solution for second question:
Let g(x) = 0
2x-1 = 0
2x = 0+1
x = 1/2
g(1/2) = 2*1/2-1
g(1/2) = +1-1
g(1/2) = 0
Hence, g(1/2) = 0 is the value of the given polynomial.
